In a new study based on surveys of hikers in New Hampshire's White Mountain National Forest, Brown University researchers find that many people hit the trails without essential equipment, often because they don't think it's needed for short hikes. Young, inexperienced hikers were most likely to...

Wind energy capacity is growing rapidly in the cold climates of the world. According to the latest forecasts, between 45 and 50 gigawatts of wind energy will be built in cold climates by 2017, which would mean an increase of as much as 72 percent since the end of 2012 and investments amounting to...

Among men with prostate cancer, African Americans experience longer treatment delays after being diagnosed than Caucasians. That is the finding of an analysis published early online in CANCER, a peer-reviewed journal of the American Cancer Society. The study suggests that efforts are needed to reduce racial disparities in...

Humans and most mammals can determine the spatial origin of sounds with remarkable acuity. To accomplish this small daily miracle, the brain has developed a circuit that's rapid enough to detect the tiny lag that occurs between the moment the auditory information reaches one of our ears, and the moment it reaches the other. The...
